Description

Porcelain Prop
RF-507

Porcelain Prop may be used to support pieces in firing
which, because of design, may require support to prevent distortion.
Simply pack the Porcelain Prop tightly under appendages or areas which
may collapse or warp. Porcelain Prop is a ceramic fiber product. It
can be fired to Cone 10 and is reusable. (12” x12” x 1”).

Gum Solution
(Plasticizer)

A liquefied binder, thickener, suspension and brushing
medium agent made of an organic cellulose gum. Also used to increase
plasticity of clay bodies.

Darvan #7
(Dispersal)

A deflocculant that is user friendly because it has
a wide deflocculation curve. Does not deteriorate molds as actively
as does sodium silicate.

Darvan #811
(Dispersal)

Similar in use and composition to Darvan #7, but recommended
for deflocculating red slips and high iron slips.

Poly 211

An alternative to sodium silicate or dispersal and
ideal when deflocculation is affected by the water or the clays within
the body. Particularly useful when thick slurries are desired.

Sodium Silicate

Liquid “N” brand Sodium Silicate is used
as a major deflocculant in preparing slip. It reduces the amount of
water needed, therefore reducing shrinkage. This is a pure sodium
silicate and must be mixed with water to a 50/50 solution for most
casting bodies.

Agent A

An additive to slip and moist clay which controls bacteria,
mold and fungus growth, hence reducing odor and gas induced pinholing
in greenware. The maximum addition to any slip should not exceed 4.5
grams per 100 pounds of dry body. Prices are per pound.
